The largest carnivore on land is the polar bear (Ursus maritimus). These magnificent creatures can weigh up to 1,500 pounds and measure about 8 feet in length. Polar bears are primarily found in the Arctic regions, relying on sea ice to hunt seals, their main food source. They have adaptations, such as a thick layer of fat and fur, to survive the freezing temperatures. Their status as apex predators places them at the top of the Arctic food chain, although they face threats from climate change and habitat loss, which impact their hunting grounds and migration patterns.
